We caught up with Samantha Ronson in Malibu over the weekend, and when asked about her thoughts on Whitney Houston's passing, the DJ told us, "It's tragic, really sad." So how did she react when we mentioned her former flame, Lindsay Lohan? You'll have to watch the video to see!

Justin Bieber, who is just weeks away from turning 18, is showing off his developing pecs while horsing around at the beach in Malibu with stepbrother Jaxon.

The "Baby" singer, sporting a beanie and his numerous tattoos, enjoyed swinging the little tot around in the sand while his dad, Jeremy, looked on. Be careful, Biebs ... you don't want to pull your little bro's arms out of the socket!

Nothing like bonding on the beach in the 'bu!

Even at the gym, she looks pretty glam!

This morning Kim Kardashian continued her fitness kick with an early workout in the valley, and afterward she tweeted, "I really pushed myself today extra hard at Barry's Bootcamp today! Great way to start my day! #YouCanGoHardOrYouCanGoHome"

Over the weekend Kim was spotted with ex-boyfriend Reggie Bush, and the former lovebirds shared an intimate lunch date at the Beverly Hills hotel, according to sources for TMZ. It's not clear if the duo are getting back together, but they were in a serious relationship for over two years, so compared to her 72-day marriage to Kris Humphries, they definitely have some history!

Well, the former Simple Life star did most of the dazzling, but no biggie!

Nicole Richie and Joel Madden attended the Grammy Awards after party at the Chateau Marmont last night, and the hot couple put on their Sunday evening best and mingled with stars like Jared Leto, Drake and Alessandra Ambrosio. Ahh, lifestyles of the rich and the famous...

Seraphina Affleck is one lucky little girl!

The 3-year-old tot commanded 100% attention from both of her famous parents ... a clean-shaven Ben Affleck and a very pregnant Jennifer Garner.

Any day now, Seraphina will be a big sis to her new sibling. Looks like 6-year-old daughter Violet had better things to do than spend the weekend with mom and dad.

No doubt, they are one of the cutest families in Hollywood!

Looks like Demi Lovato likes changing her hair as much as Lindsay Lohan did back in the day!

The 19-year-old Disney starlet dyed her dark red locks blonde over the weekend, and she tweeted this photo and wrote, "Thank you SO much Nine Zero One salon for my new locks!! How do you guys like the new look?? :)"

Shortly after the pic hit the web, Demi's new hue become a trending topic, and the singer/actress wrote, "Ahhhahaha Demi Blondevato is a trending topic?!! Y’all are funny! Haha." What do YOU think about Demi's lighter locks?

Whitney Houston's funeral will be held in Newark, New Jersey, according to NBC New York.

The 48-year-old singer, who died in Beverly Hills on Saturday, will reportedly have her service arranged by Whigham Funeral Home ... the same place that handled her father's funeral back in 2003.

Hundreds of signs and flowers have been left outside a Newark church in honor of the late singer. This particular church is where Houston sang as a child.

For now, Whitney's cause of death is still unknown, but reports claim Houston was found underwater in the bathtub of her Beverly Hilton hotel room just before 3:30pm Saturday. Emergency services responded in 20 minutes and made multiple attempts to revive the singer, without success. Houston was pronounced dead at 3:55pm.

David and Victoria Beckham took their infant daughter Harper to Balthazar in New York City over the weekend, and the trio were dressed to the nines for their late afternoon meal.

Before their lunch date, the superstar couple handed Harper off to the nanny and attended Victoria's Autumn/Winter 2012 collection show, where David sat right next to Anna Wintour in the front row.

Posh noted that her new line was designed "to create an emotional attachment between the garment and the wearer. The idea of how the body can connect to the clothes through their construction and detail fascinates me." With a handful of celebrity guests (not to mention tons of praise from fashion critics), it sounds like Victoria's show was a smash success!
